BOTTLE STOPPER SPECIFICATION forming part of Letters Patent No. 380,957, dated April 10. 1888. Application filed September t3, 1886. Serial No.212,821. (No model.)

To aZZ whom it may concern:

Be it known that I, SELDEN TWITCHELL, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvementin Bottle-Stoppers,which improvement is fully set forth in the following specification and accompanying drawing, in which the figure represents a vertical section of a bottle-stopper embodying my invention, this consisting of a bottle having the inner inclined Wall of its neck formed with a depending angular projection forming a seat for the elastic rim of a buoyant ball, the said rim being secured in a peripheral groove of said ball, substantially as described.

Referring to the drawing, A represents a ball or head, formed of wood or other buoyant material, and having a circumferential groove, B, which is occupied by a rim, 0, of soft rubber or other elastic material, said rim projecting beyond. the periphery of the ball A, and, for the purpose of securing, being sprung into the groove. The groove B of the ball has preferably a central ridge, and the rim 0 has inner projecting ridges with sloping sides corresponding to the form of the groove B. By this construction the rim is adapted to fit tightly to said ball, embracing the walls of the groove and ridge thereof, and is therefore not easily displaced therefrom when the ball is forced upward.

D represents an annular projection on the inner face of the neck of the bottle, furnishing a depending angular-shaped seat, a, for the elastic rim of the stopper. The walls of the neck are inclined inward, as at b, from the body of the bottle, for a purpose hereinafter set forth.

downwardinto the bottle by any suitable g means, and when it leaves its seat it reaches the fluid and floats thereon instead of dropping to the bottom, which latter action often breaks the stopper and bottle.

It will also be seen that packing of the neck is avoided and special construction of the neck to hold such packing obviated, so that the stopper presented by me is simple and inexpensive in its nature.

I am aware that it is not new to provide a buoyant stopper with an elastic rim, and such I do not broadly claim. I

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

A bottle having on the inner wall of its neck an annular projection with the depending angular seat a, the said neck having an inclined portion, as at b, in combination with a buoyant ball with peripheral groove and provided with an elastic rim secured in said groove, all substantially as and for the purpose set forth.
